Yesterday, I knocked over my bike while it was running. While laying on it side it was still running until I attempted to pick it up and the rear tire touch the ground, it was down for about 5 to 10 seconds.

Once up, tried to start it, took about 5 seconds of cranking before it start running, then I notice is was mis-firing. Drove it around the block and still mis-fireing. Had to ride home 1 hr ride and once I got to a stop light it was still doing the samething. I had a hour of highway riding, thinking it should run better, acceleration is good, no bike drag. Just at idle it is the mis-fire.

Any clue, I haven't taking it apart yet.

It wasn't a hard fall, it lean over to far for my to hold it, because of the way my hand was position. So, it did a little dumph, nothing hard at all.

 

Keep starting it and running it. One of your plugs may have fouled out. It happened to me also. I kept rolling and it eventually cleared up. If it don't then check your spark plugs.

 

maybe one o your wires got damaged.
